Can you link us to a photo that shows what you are referring to?
Is this a hot-water boiler? Don't drain it to remove rust. That will require more make-up water, with entrained air/oxygen, which will just cause more corrosion. Draining to eliminate rust is a never-ending process. A sealed hot-water system should only produce harmless black water when drained. Do you have an appropriate air-removal device, and is it working?
